Scientists Are Trying to Teach AI How to Smell科學(xué)家嘗試讓人工智能獲得嗅覺

Describing odors can be surprisingly complicated， even for a complex computer.

用文字來描述氣味，即便是借助于復(fù)雜的計算機系統(tǒng)，也可能會出人意料地困難。

It’s hard to overstate the power of the nose—research says humans can distinguish more than a trillion odors. This is especially impressive when you remember that each individual odor is a chemical with a unique structure. Experts have been trying to discern patterns or logic in how chemical structure dictates smell， which would make it much easier to synthetically replicate scents or discover new ones. But that’s incredibly challenging—two very similarly structured chemicals could smell wildly different. When identifying smells is such a complicated task， scientists are asking： Can we get a computer to do it？
